Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...
The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
The renewed TC12/ESIS technical committee - Risk analysis and safety of large structures and components
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The ESIS Executive Committee decided to nominate a new team for the leadership and management of the TC12/ESIS technical committee (TC), as well as update the TC name as "Risk Analysis and Safety of Large Structures and ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability based ...
Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...
Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
XFEM based analysis of fatigue crack growth in damaged wing-uselage attachment lug
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The research presented in this paper is based on the use of extended finite element method (XFEM) for stress intensity factors (SIFs) determination in the case of fatigue crack presented in the wing-fuselage attachment lug ...
Structural integrity and life assessment of rotating equipment
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Failures of rotating equipment often cause severe consequences, so it is necessary to study their integrity and life as detailed as possible, especially when crack is detected. In the case studied here, hydro power plant ...
